Carefully.

I think the portion relevant to you is:
     "A single backplane system does not require termination if there are
     less than 20 AC loads."
That's why on Saturday I recommended just skipping the termination on
your small box (four quad slots, not full).  On your large box, termination
may well be necessary if lots of cards are installed.
